Course Description
Drawing and Specification Requirements for Seismic Design
July 21, 2016
Design drawings and specifications are integral parts of structural steel
contracts. They must accurately convey the work to be performed in
order to ensure accurate bids and safe projects. Both the AISCCode of
Standard Practiceand the AISCSeismic Provisionscontain requirements
related to the information that must be provided to the contractor by
the engineer of record.
This presentation will provide an overview of the relevant AISC
documents and their requirements pertaining to seismic design. The
presenters will discuss the effect incomplete information can have on
the bidding process and some common issues they have seen in
practice. Examples of how to properly include the requisite information
will be provided.

Learning Objectives
• Gain an understanding of the required information that must be
provided in the contract documents by the engineer of record to the
contractor.
• Become familiar with the AISCCode of Standard Practiceand the
AISCSeismic Provisions and their requirements pertaining to seismic
design.
• Understand some of the common issues related to drawing and
specification requirements for seismic design including incomplete
bid documents, excessively applying requirements through
misinterpretation, and undefined connection configurations.
• Become familiar with how to present the required information
contract documents through the review of real‐world examples of
drawings, details, notes and specifications.

Why is this presentation
necessary?

Eight Years Ago
A presentation was given on this topic about 8 years
ago. At that time:
• Many engineers and fabricators were still
unfamiliar with the Seismic Provisions.
• Prequalified moment connections were relatively
new.
• The length of the Seismic Provisions had nearly
doubled and the number of projects subject to its
requirements increased significantly.

Eight Years Ago
• Engineer’s drawings and specifications often
lacked basic information.
• The final cost of some projects were multiples of
the bid price.
• Many engineers did not understand capacity‐
based design.
–Connections were often required to resist
forces greatly in excess of those that could be
resisted by the members.
13
Today
• Engineers and fabricators are more
knowledgeable about seismic design
• The Seismic Provisions have stabilized.

• It is a new day and our problems are behind
us.

Why do we need to provide all
this information?

Why? SAFETY
Structural engineers provide information related
to the design and construction of buildings.
If you want the building to perform the way you
intend, then the information you provide must
be clear and accurate.
17
Why? MONEY
• Meeting the Seismic Provisions increases the
cost of projects.
• Fabricators bid what they see.
• When the $cope of work change$ from that
e$tabli$hed in the Contract Document$, a
modification of the contract price $hall be
made. (paraphrased from the CO$P)

The Contractors’ Dilemma
Bid what I see and Bid what I think the
fight for extras engineer wants and
later. lose the project to a
lower bidder.
